Why Pool Choice Actually Matters
Solo mining Bitcoin at anything short of industrial scale has an astronomically low chance of ever finding a block. Pools combine hashrate across thousands of miners so everyone gets small, steady, predictable payouts instead of a lottery ticket. But not all pools pay the same way, and the difference between a well-chosen and poorly-chosen pool shows up directly in your monthly hash price — the same rig on the same algorithm can earn measurably more or less over a year depending purely on which pool it's pointed at.
This matters more than most buying guides admit, because the pool layer sits on top of everything else you've already decided: the ASIC model, the algorithm, the power price. Get the hardware right and then hand it to a badly-chosen pool, and you're leaving money on the table for no reason.
The State of the Network Right Now
Bitcoin's network hashrate has been running roughly 886–934 EH/s through mid-September 2026, with difficulty at 127.45 trillion after a 1.31% upward adjustment at block 965,664 on September 6, 2026 (Hashrate Index). Pool concentration is worth knowing about before you pick one: Foundry USA currently holds around 24.4% of network hashrate, AntPool about 21%, and F2Pool roughly 16.25%. The top three control close to 61.6% of the network, and the top four — Foundry USA, AntPool, F2Pool and ViaBTC — control nearly 70% between them (Squaredtech, Shattered.io). That concentration doesn't make a large pool unsafe to use — it does mean your payout variance is going to look different on a 24%-share pool than on a 3%-share one, which is the factor most beginners underweight.
The Factors That Actually Move Your Returns
Fee Structure
Fees vary by pool, by coin, and by which payout scheme you pick within that pool — they are not one flat number. On Bitcoin specifically: Foundry USA is commonly listed at 0% under its FPPS model (MiningPoolStats), AntPool offers FPPS around 2.5% or PPLNS at 0% (AntPool support), F2Pool charges 4% on FPPS, 2.5% on PPS+, and 2% on PPLNS (F2Pool help center), and ViaBTC runs PPS+ at 4% and PPLNS at 2% (ViaBTC pricing). Braiins Pool charges 2% on FPPS and its Score-based scheme, rebated to an effective 0% if you run their Braiins OS+ firmware (Braiins Academy). A 0% headline fee is real, but always check which scheme it applies to — a pool's 0% option is often the higher-variance PPLNS tier, not the smoother FPPS one.
Payout Method
| Method | How it works | Best for |
|---|---|---|
| PPS (Pay Per Share) | Fixed payment per share submitted, pool absorbs variance | Predictable income, slightly lower average |
| PPS+ (Pay Per Share Plus) | PPS for the block reward, plus a PPLNS-style split of transaction fees | Stable base income with some upside |
| PPLNS (Pay Per Last N Shares) | Paid based on recent shares when a block is found | Lower fees, more variance |
| FPPS (Full Pay Per Share) | PPS plus a fixed, averaged share of transaction fees | Best overall average returns, most predictable |
FPPS and PPS+ both try to give you transaction-fee revenue without full PPLNS variance, but they do it differently: FPPS averages the fee income across a longer window, while PPS+ distributes the fee portion PPLNS-style, so it swings more than FPPS while your block-reward portion stays fixed either way.
Pool Size and Payout Variance
Larger pools find blocks more often, which smooths out your payout schedule — this is the direct consequence of the concentration numbers above. A 24%-share pool finds a block roughly every 4 blocks worth of network time; a 3%-share pool finds one roughly every 33. Smaller pools have larger but rarer individual payouts under PPLNS-style schemes; under PPS or FPPS, pool size mostly stops mattering for your payout smoothness because the pool is fronting the variance, not you.
Minimum Payout and Server Locations
Lower minimum payout thresholds mean faster access to your earnings — more relevant for smaller home-scale miners than large operations paying out daily regardless. Server location matters for round-trip latency to the pool, which affects share submission and, at the margin, orphan/stale share rates. If you're running hardware from Hong Kong, the UAE, or elsewhere outside North America, check whether the pool has an Asia-Pacific or Middle East server endpoint rather than routing every share to a US or EU-only stratum address — most of the pools below (F2Pool, AntPool, ViaBTC) operate multi-region servers for exactly this reason, while Foundry USA and Braiins Pool are more US/EU-centric in their primary infrastructure.
Top Bitcoin Mining Pools Compared (2026)
| Pool | Network Share | Fee | Payout Scheme | Notable Feature |
|---|---|---|---|---|
| Foundry USA | ~24.4% | 0% (FPPS) | FPPS | Largest pool by share; primarily industrial/institutional accounts |
| AntPool | ~21% | 2.5% (FPPS) or 0% (PPLNS) | FPPS/PPLNS/PPS+ | Bitmain-affiliated, broad multi-coin and merged-mining support |
| F2Pool | ~16.25% | 4% (FPPS) / 2.5% (PPS+) / 2% (PPLNS) | FPPS/PPS+/PPLNS | Widest algorithm coverage of the major pools, multi-region servers |
| ViaBTC | part of top-4 ~70% combined | 4% (PPS+) / 2% (PPLNS) / 1% (Solo) | PPS+/PPLNS/Solo | Per-coin payout choice, solo-mining option on the same account |
| Braiins Pool | smaller, legacy "Slush Pool" | 2%, rebated to ~0% with Braiins OS+ | FPPS/Score | Stratum V2 native — encrypted, bandwidth-efficient connection |

Matching Pool Choice to Your Hardware's Algorithm
Pool selection isn't just a Bitcoin question. Our catalog spans several algorithms, and each one has a different, smaller pool of pools to choose from.
SHA-256 (Bitcoin) — the deepest pool market by far, covered by every pool in the table above. This is what runs on our Antminer S19j Pro, Avalon A1246, and Whatsminer M50 — see the full range in Bitcoin Miners.
Scrypt (Litecoin, merged-mined with Dogecoin) — F2Pool and ViaBTC both run Scrypt pools with LTC/DOGE merged mining, meaning your hashrate earns DOGE rewards on top of LTC at no extra hashrate cost; F2Pool lists a 4% PPS fee on this pair, ViaBTC splits 4% PPS+ / 2% PPLNS by coin. Hardware like our Antminer L9 runs Scrypt — browse the range in Litecoin & Scrypt Miners.
KHeavyHash (Kaspa) — F2Pool, AntPool and ViaBTC all run Kaspa pools; ViaBTC lists PPS+ (4%), PPLNS (2%), and a 1% solo option specifically for KAS. Our Antminer KS5 and the IceRiver KS-series run this algorithm — see Kaspa Miners.
Everything else — Eaglesong (Nervos CKB), Blake3 (Alephium), Blake2S (Kadena), AleoBFT (Aleo), X11 (Dash), and Handshake all run on hardware we stock (Goldshell, IceRiver and iBeLink models in particular), but each has a much smaller circle of pools than SHA-256, Scrypt or KHeavyHash. Verify current pool support and published fees directly on the coin's own mining-pool listing before buying — support for niche algorithms shifts faster than for Bitcoin, and a pool that supported an algorithm last year isn't guaranteed to still run it.

Security Basics
Whichever pool you land on, the return you actually see also depends on your power price and the machine itself — run your numbers through our profitability calculator and use compare if you're deciding between two ASIC models before you commit hashrate to any pool. Pool choice doesn't affect your hardware warranty either way — that's covered separately under our repair and warranty terms.
